R307-349. Flat Wood Paneling Coatings |
| R307-349-1. Purpose |
|
Latest version.
|
|
The purpose of R307-349 is to limit volatile organic compound (VOC) emissions from flat wood paneling coating sources. |
| R307-349-2. Applicability |
|
Latest version.
|
|
(1) R307-349 applies to flat wood paneling coating operations located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber counties. (2) Before September 1, 2018, R307-349 applies to flat wood paneling coating operations that have the potential to emit 2.7 tons per year or more of VOC, including related cleaning activities. (3) Effective September 1, 2018, R307-349 shall apply to flat wood paneling coating operations that use a combined 20 gallons or more of coating products and associated solvents per year. |
| R307-349-3. Definitions |
|
Latest version.
|
|
The following additional definitions apply to R307-349: "As applied" means the VOC and solids content of the finishing material that is actually used for coating the substrate. It includes the contribution of materials used for in-house dilution of the finishing material. "Finishing material" means a coating used in the flat wood panel industry, including basecoats, stains, washcoats, sealers, and topcoats. "Flat wood paneling" means wood paneling products that are any decorative interior, exterior or tileboard (class I hardboard) panel to which a protective, decorative, or functional material or layer has been applied. "Strippable booth coating" means a coating that is applied to a booth wall to provide a protective film to receive overspray during finishing and that is subsequently peeled and disposed. Strippable booth coatings are intended to reduce or eliminate the need to use organic solvents to clean booth walls. |

|
Latest version.
|
|
(1) No owner or operator shall apply coatings with a VOC content greater than 2.1 pounds of VOC per gallon, excluding water and exempt solvents (compounds not classified as VOC as defined in R307-101-2), unless an add-on control device is used as specified in R307-349-6. (2) No owner or operator shall use a strippable booth coating with a VOC content greater than 3.8 pounds VOC per gallon, excluding water and exempt solvents (compounds that are not defined as VOC), unless an add-on control device is used as specified in R307-349-6. |
| R307-349-5. Work Practice |
|
Latest version.
|
|
(1) The owner or operator shall: (a) Store all VOC-containing coatings, thinners, and cleaning materials in closed containers; (b) Minimize spills of VOC-containing coatings, thinners, and cleaning materials; (c) Clean up spills immediately; (d) Convey any coatings, thinners, and cleaning materials in closed containers or pipes; (e) Close mixing vessels that contain VOC coatings and other materials except when specifically in use; and (f) Minimize usage of solvents during cleaning of storage, mixing, and conveying of equipment. (2) No person shall apply any coating unless the coating application method achieves a demonstrated 65% transfer efficiency. The following applications achieve a minimum of 65% transfer efficiency and shall be operated in accordance with the manufacturers specifications: (a) Paint brush; (b) Flow coat; (c) Roll coat; (d) Dip coat; (e) Detailing or touch-up guns; (e) High-volume, low-pressure (HVLP) spray; (f) Hand application methods; or (g) Other application method capable of achieving 65% or greater transfer efficiency, as certified by the manufacturer. (3) No owner or operator shall perform solvent cleaning operations using materials with a VOC composite vapor pressure greater than 1 mm Hg at 20 degrees Celsius, unless an add-on control device is used as specified in R307-349-6. |
| R307-349-6. Add-On Controls Systems Operations |
|
Latest version.
|
|
(1) If an add-on control system is used, the owner or operator shall install and maintain the add-on emission control system in accordance with the manufacturer recommendations and maintain 90% or greater capture and control efficiency. The overall capture and control efficiency shall be determined using EPA approved methods, as follows. (a) The capture efficiency of a VOC emission control system's VOC collection device shall be determined according to EPA's "Guidelines for Determining Capture Efficiency," January 9, 1995 and 40 CFR Part 51, Appendix M, Methods 204-204F, as applicable. (b) The control efficiency of a VOC emission control system's VOC control device shall be determined using test methods in Appendices A-1, A-6, and A-7 to 40 CFR Part 60, for measuring flow rates, total gaseous organic concentrations, or emissions of exempt compounds, as applicable. (c) An alternative test method may be substituted for the preceding test methods after review and approval by the EPA Administrator. |
| R307-349-7. Recordkeeping |
|
Latest version.
|
|
(1) The owner or operator shall maintain records of the following: (a) Records that demonstrate compliance with R307-349. Records shall include, but are not limited to, inventory and product data sheets of all coatings and solvents subject to R307-349. (b) If an add-on control device is used, records of key system parameters necessary to ensure compliance with R307-349-6. (i) Key system parameters shall include, but are not limited to, temperature, pressure, flow rates, and an inspection schedule. (ii) Key inspection parameters shall be in accordance with the manufacturer's recommendations, and as required to demonstrate operations are providing continuous emission reduction from the source during all periods that the operations cause emissions from the source. (2) All records shall be maintained for a minimum of 2 years. (3) Records shall be made available to the director upon request. |
